The finding that there appears to be only one relevant essential coupling in QEG is an encouraging sign for attempts to make contact with other methods which can be used to investigate asymptotic safety. In particular, it would be very interesting if perturbative methods based on expansions around two dimensions [1]}, [2]}, [3]} could also calculate the critical exponent \(\)  by performing a two-loop calculation in the minimal essential scheme. Additionally, the value of \(\)  can be computed in lattice and tensor model approaches to quantum gravity [4]}, [5]}, [6]}, [7]}.
